Morphemic analysis.
The segmentation of words is generally carried out according to the method of Immediate and Ultimate Constituents. This method is based upon the binary principle, i.e. each stage of procedure involves two components the word immediately breaks into. At each stage these two components are referred to as the Immediate Constituents (IC)⁶. Each IC at the next stage of analysis is in turn broken into smaller meaningful elements. The analysis is completed when we arrive at constituents incapable of further division, i.e. morphemes. These are referred to as Ultimate Constituents (UC). The analysis of word-structure on the morphemic level must naturally proceed to the stage of UC-s.
Allomorphes are the phonemic variants of the given morpheme e.g. il-, im-, ir-, are the allomorphes of the prefix in- (illiterate, important, irregular, inconstant).
Monomorphic are root-words consisting of only one root-morpheme i.e. simple words (dry, grow, boss, sell).
Polymorphic are words consisting of at least one root-morpheme and a number of derivational affixes, i.e. derivatives, compounds (customer, payee, body-building, shipping).
Derived words are those composed of one root-morpheme and one more derivational morphemes (consignment, outgoing, publicity).
Derived words are those composed of one root-morpheme or more. Compound words contain at least two root-morphemes (warehouse, camera-man),
Productivity is the ability to form new words after existing patterns which are readily understood by the speakers of a language. Synchronically the most important and the most productive ways of word-formation are affixation, conversion, wordcomposition and abbreviation (contraction). In the course of time the productivity of this or that way of word-formation may change. Sound interchange or gradation (blood - to bleed, to abide -abode, to strike - stroke) was a productive way of word building in old English and is important for a diachronic study of the English language. It has lost its productivity in Modern English and no new word can be coined by means of sound gradation. Affixation on the contrary was productive in Old English and is still one of the most productive ways of word building in Modern English.
Affixation is the formation of new words with the help of derivational affixes. Suffixation is more productive than prefixation. In Modern English suffixation is a characteristic of noun and adjective formation, while prefixation is typical of verb formation (incoming, trainee, principal, promotion).
Affixes are usually divided into living and dead affixes. Living affixes are easily separated from the stem (care-ful). Dead affixes have become fully merged with the stem and can be singled out by a diachronic analysis of the development of the word (admit - L.- ad + mittere)⁷. Living affixes are in their turn divided into productive and non-productive affixes. In many cases the choice of the affixes is a mean of differentiating of meaning: uninterested - disinterested distrust – mistrust.
Word-composition is another type of word-building which is highly productive. That is when new words are produced by combining two or more stems.
Stem is that part of a word which remains unchanged throughout its paradigm and to which grammatical inflexions and affixes are added. The bulk of compound words is motivated and the semantic relations between the two components are transparent.
Compound words proper are formed by joining together stems of words already available in the language. Compound proper is a word, the two Immediate Constituents of which are stems of notional words, e.g. ice-cold (N + A), illluck(A+N).
Derivational compound⁸ is a word formed by a simultaneous process of composition and derivation. Derivational compound is formed by composing a new stem that does not exist outside this pattern and to which suffix is added. Derivational compound is a word consisting of two Immediate Constituents, only one of which is a compound stem of notional words, while the other is a derivational affix, e.g. blue - eyed - (A+N) + ed In coordinative compounds neither of the components dominates the other, both are structurally and semantically independent and constitute two structural and semantic centres, e.g. breath-taking, self-discipline, word-formation.
